Firefox Community Forum

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

I know Firefox is slow when opening Facebook. It's busy blocking all their crap. But recently it's been super slow and non-connective to many sites I visit often. I've Ookla checked my connectivity and their excellent. Logging into sites I've visited before is now taking a long time some having to be resent. IE: www.clevelandclinic.org, local government sites etc.
